Application of 5456-63-3, Adding some certain compound to certain chemical reactions, such as: 5456-63-3, name is trans-2-Aminocyclohexanol hydrochloride,molecular formula is C6H14ClNO, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 5456-63-3.
a) 5-Bromo-N-((1SR,2RS)-2-hydroxy-cyclohexyl)-6-(2,2,2-trifluoro-ethoxy)-nicotinamide 5-Bromo-6-(2,2,2-trifluoro-ethoxy)-nicotinic acid (75.0 g, 0.25 mol) was dissolved in DMF (850 mL). To the solution was added TBTU (91.0 g, 0.275 mol), N,N-diisopropylethyl amine (214 mL, 1.25 mol) and (1SR,2RS)-2-amino-cyclohexanol hydrochloride (41.7 g, 0.275 mol). The reaction mixture was stirred for 1.5 h at room temperature. The solvent was evaporated in vacuo, the residue was partitioned between ethyl acetate (2500 mL) and 1 N sodium hydroxide solution (2000 mL), the water phase was separated, extracted once more with ethyl acetate (1000 mL) and the organic phases were washed 2 times with water (2*1500 mL). Organic phases were pooled, dried with MgSO4 and concentrated to about 900 mL. The product precipitated upon stirring and cooling to 0 C. Filtration, washing with ethyl acetate/n-heptane (1:1) and drying in vacuo gave the title compound (81.1 g) as a white solid; MS (ISP) 397, 399 (M)+.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 5456-63-3, trans-2-Aminocyclohexanol hydrochloride, other downstream synthetic routes, hurry up and to see.
